Control circuit specifications
The functions of the terminals highlighted in grey can be adjusted with parameters 178 to 182
"Input terminal function assignment" and Pr. 190, Pr. 192 or Pr. 197 "Output terminal function as-
signment" (refer to section 6.9). The listed settings show the default configuration as shipped,
which you can restore by resetting to the factory defaults.

Turn on the STF signal to
start forward rotation and
turn it off to stop.
When the STF
and STR signals
are turned on
simultaneously,
the stop com-
mand is given.

4 to 6mA DC
STR
Reverse rotation
start
Turn on the STR signal to
start reverse rotation and
turn it off to stop.
RH, RM, RL
Multi-speed
selection
Multi-speed can be selected according to the
combination of RH, RM and RL signals.

supply common
A determined control function is activated, if
the corresponding terminal is connected to the
terminal SD (sink logic).
The SD terminal is isolated from the digital
circuits via opto-couplers. The terminal is
isolated from the reference potentials of the
analog circuit (terminal 5) and the open
collector outputs (terminal SE).

common (source)
24V DC/0.1A output
With negative logic and control via open col-
lector transistors (e.g. a PLC) the positive pole
of an external power source must be con-
nected to the PC terminal. With positive logic
the PC terminal is used as a common refer-
ence for the control inputs. This means that
when positive logic is selected (default setting
of the EC units) the corresponding control
function is activated by connecting its terminal
to the PC terminal.
